Xác định a, b để \(f\left(x\right)⋮g\left(x\right)\)
a) \(f\left(x\right)=2x^3-3x^2+ax+b\)
\(g\left(x\right)=x^2+x+2\)
b) \(f\left(x\right)=2x^4+ax^2+b\)
\(g\left(x\right)=x^2-x-3\)
c) \(f\left(x\right)=3x^4-8x^3-10x^2+ax-b\)
\(g\left(x\right)=3x^2-2x+1\)
d) \(f\left(x\right)=ax^3+bx^2-11x+30\)
\(g\left(x\right)=x^2-3x-10\)
